Mr. Hume was afterwards associated with a Mr. Hovel, in an excursion to the south coast, under the auspices of Sir Thomas Brisbane. After a most persevering and laborious journey, they reached the sea; but it is uncertain whether they made Port Philips, or Western Port. Mr. Hume, whose practical experience will yield to that of no man, entertains a conviction that it was to the former they descended from the neighbouring ranges; but Mr. Hovel, I believe supports a contrary opinion. In the early stage of their journey, they passed over York or Yass Plains; and, after crossing the Morumbidgee, were generally entangled among mountain ranges that increased in height to the east and south-east. They crossed three considerable rivers, falling westerly, which they named the Goulburn, the Hume, and the Ovens; and found a beautiful and well-watered country in the vicinity of the coast. In 1826, Mr. Allan Cunningham, Botanical Collector to his late Majesty, traversed a considerable portion of the interior to the north of Bathurst, and, with a laudable zeal, devoted his labours to the acquisition of general information, as well as to his more immediate professional pursuits. In 1827, this gentleman again bent his steps towards the northward, and succeeded in gaining the 28th parallel of latitude; and, on a subsequent occasion, having taken his departure from Moreton Bay, he connected his former journey with that settlement, and thus contributed largely to our knowledge of the mountain country between it and the capital. Mr. Cunningham, who, independently of his individual excursions, had not only circumnavigated the Australian Continent with Capt. King, but had formed also one of the party with Mr. Oxley, in the journeys before noticed, had adopted this gentleman's opinion with regard to the swampy and inhospitable character of the distant interior. Its depressed appearance from the high ground on which Mr. Cunningham subsequently moved, tended to confirm this opinion, which was moreover daily gaining strength from the reports of the natives, who became more frequent in their intercourse with the whites, and who reported that there were large waters to the westward, on which the natives had canoes, and in which there were fish of great size. It became, therefore, a current opinion, that the western interior of New Holland comprehended an extensive basin, of which the ocean of reeds which had proved so formidable to Mr. Oxley, formed most probably the outskirts; and it was generally thought that an expedition proceeding into the interior, would encounter marshes of vast extent, which would be extremely difficult to turn, and no less dangerous to enter.
